SPECIFICATION forming part of Letters Patent N 0. 510,127, dated December 5, 1893.

Application filedMay 2, 1893. serial No. 472,689. (No model.)

To all whom it may concern.-

Be it known that we, ZAOHARY '1. FRENCH and WILLIAM G. MEYER, of Boston, county of Sufiolk, State of Massachusetts, have in-' vented an Improvement in Sole-Gouging Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

In the manufacture of some classes or styles of boots and shoes it is desired to gouge into or remove from the inner or shank part of a sole a portion of the leather so as to enable the leather to be bent outwardly andprcsent a swelled or other than flat shank.

In accordance with our invention the sole to be gouged is laid upon a suitable support with its inner face uppermost, and while held in shape, a gouge is made to approach, cut into, and remove a portion of the leather for a short distance and then to retire from the leather leaving a hollow space or gouged groove therein, the relative positions of the gouge and support being changed during the gouging operation to thus enable a longer or shorter gouge out to be made.

In the present embodiment of our invention the gouge is made to travel over the support, but a converse movement would effect just the same result.

Figure 1, in side elevation represents a sole gouging machine embodying our invention; Fig. 2, a top or plan view thereof; Fig. 3a detail of the cam track; Fig. 4 a section of a sole gouged at the shank; and Fig. 5 shows the gouged sole bent as it will be in practice.

In the drawings A, represents part of a suit-' able bench or column to sustain the framework A of our invention. The frame-work. referred to has suitable bearings A to receive a shaft B and is provided with suitable, fast and loose pulleys B, B adapted to be driven in any usual way, and with a pinion B The frame-work has other bearings A in whichv is, in this present instance of our invention, fitted to slide a rock-shaft 0, said rock-shaft having suitably clamped upon it by a screw 0' a cutter carrier 0 the hub of said carrier being split and clamped upon the said slide-rod by a set screw. The carrier has attached to it a rack C which is adapted to be engaged by a pinion 13 so that the latter slides the carrier longitudinally during the gouging operation. The carrier 0 has fixed to it byasuitable bolt a, a gouge carrier a, in groovesin which are adj ustably held by suitable set screws a 0. gouges b, b. The carrier is represented as provided with a projection 0, preferably in the form of a roll, which is adapted to roll upon the upper edge of a cam track composed preferably of two plates d, d placed side by side and clamped in adjusted position by means of clamp screws d the upper edges of said cam track being suitably shaped, see Fig. 3, to, by their adjustment, let the gouges b, b descend sooner or later to contact with the leather or sole to be gouged and to remain in contact with the said leather or sole for a greater or less extent, the stroke of the carriage having been sufficient to gouge out a groove of sufficient length, serving to lift the carrier and effect the disengagement of the rack C from the pinion B The leather orsole to be gouged will be laid upon the bed e of the frame-work under the presser-feet e, e pivoted upon studs 0 e shown bydotted lines Fig. 3, and held in position by set screws 10 in cars 12. Each presser-foot is of elbow shape, or has a depending arm, as 13, to which is attached a rod 14,.the two like rods from the two like arms 13, 13 being attached to a suitable bar or cross head 15 having an attached rod lfi in practice connected with some suitable treadle, so that as the rod 16 is depressed the feet will be thrown down on the leather to clamp it firmly in place while the gouge acts. The springs 6 c act normally to elevate the presser-feet when downward pressure on the rod 16 is removed.

Fig. 4-, shows a sole 8 in transverse section at theshank, the space 8' being removed by the gouge, and in Fig. 5, we have shown the gouged sole bent to cause the outer side of the shank to bulgeoutwardly.

The cam tracks by their adjustment one with relation to the other shorten or lengthen the concaved space It so as to shorten or lengthen the gouge slit. The tracks constitute a pattern surface.

This invention is not limited to the exact construction shown for the cutting gouge.

Having described our invention, what we claim, and desire to secure by Letters Patent, 1s-

1. In a sole-gouging machine, a bed-plate, the clamp consisting of feet 6, e to engage and hold the sole on opposite sides of the line of travel of the gouge, and means to hold down and release said feet, combined with a carriage and a gouge mounted thereon, means to move such carriage across the bed-plate, and a pattern surface with which the carriage cooperates to cause the gouge to enter and groove or gouge out the sole and thereafter recede or retire, substantially as described.

2. In a sole gouging machine, a bed-plate and means to clamp a sole thereon, a shaft provided with the gear 13 a pivoted and slidable carriage having a rack-bar which periodically engages the said gear to efiect the sliding movement of the carriage, and a gouge-holder and gouge therein mounted upon and movable with said carriage, combined with a pattern surface with which the carriage cooperates to efiect the periodical 3o engagement and disengagement of the rack and gear and thereby enable the gouge to gouge out a groove in the sole and then retire, substantially as described.

3. In a sole gouging machine, the following 3 5 instrumentalities, vim-the bed plate; the clamp consisting of feet c, 6 having arms 13; means to engage said arms to press said feet upon the sole lying on the bed-plate; a pivoted carriage having a rack, and a holder, and a gouge; a rotating shaft provided with a gear as B to engage said rack and reciprocate said carriage; and a pattern plate having a portion of its surface shaped to let the carriage descend and the gouge enter the sole, the descent of the carriage effecting the engagement of its rack teeth with the said gear B to operate substantially as described.

In testimony whereof we have signed our names to this specification in the presence of 50 tWo subscribing witnesses.
